3, injection pressure: can be large to 1500bar pressure: can be large to 1000bar injection speed: In order to avoid material degradation, generally with a considerable injection speed.

4, Runner and gate: All regular gate can be used. If a smaller part is machined, use a needle-shaped gate or submerged gate, and for thicker parts, use a fan gate. The minimum diameter of the needle-shaped gate or submerged gate should be 1mm, and the thickness of the fan gate should not be less than 1mm.
